Answer:

1372 , - 9604

Explanation:

there isa common ratio between consecutive terms , that is


(28)/(-4) =
(-196)/(28) = - 7

To obtain the next term in the sequence multiply the previous term by - 7

- 196 × - 7 = 1372

1372 × - 7 = - 9604

Answer:

The next 2 terms are 1372 and -9604.

Explanation:

If we look at -4 and 28, we can infer that 28 is a factor of -4. What times -4 can give us 28?

-4x(-7), -4x(-7)(-7)

This is just another way of writing the pattern.

Now we have to multiply -196 by -7, and that product by -7.

-196x-7=1372

1372x-7= -9604

So, the next 2 terms are 1372 and -9604.
